Near term Today and tonight...

a quasi-stationary front will meander across north-central
florida today as surface high pressure builds across the mid-
atlantic coast. Breezy onshore flow will develop today between
these features with winds increasing to near 15 mph along the
coast with gusts near 25 mph by midday across coastal counties and
the st. Johns river basin. Coastal showers are expected to
increase from both the atlantic and gulf coast through sunrise,
along and north of the meandering front. High moisture content
with precipitable water near 2 inches will continue to stream over
north florida today, while drier air and subsidence from the
north will limit convective growth near the altamaha river basin.

Highest rain chances this afternoon and evening will focus inland
between highway 301 and i-75 where onshore flow will converge with
a late developing west coast sea breeze front. Slow storm motion
and high moisture content will once again bring the potential for
locally heavy rainfall today, especially along and west of the st.

Johns river basin in NE florida. Rising heights aloft and warming
temperatures will tend to limit strong to severe tstorm potential
today, however wet downbursts will be possible due to precip
loading.

Rainfall potential will decrease this evening with a low chance
of mainly coastal showers continuing through the night as the
meandering front across central florida begins to lift northward
in response to a broad mid level low across the central gulf coast
states lifting nne as the high pressure ridge builds farther
offshore of the mid-atlantic. Moisture will also pivot northward,
with a coastal trough and convergence after midnight bringing a
chance of coastal showers drifting inland, especially across parts
of SE ga.

Temperatures will range in the 80s today with near 90 possible
where cloud breaks occur this afternoon. Tonight mild and above
climo temperatures as winds veer southeast with lows ranging in
the 70s with patchy fog potential after midnight through sunrise.

Thursday through Friday night... Upper ridge over S fl on Thursday
will build north into central florida on Friday. Weak mid-upper
level impulses in SW flow will move across ga which may enhance
convection over SE ga along with diurnal heating. Scattered to
numerous afternooon evening storms expected as seabreezes merge over
interior NE fl. Locally heavy rainfall with isolated strong storms
expected as a hot and humid airmass remains in place. Temperatures
will increase to near average levels Friday with pops above normal.

Long term Saturday through Tuesday... Deep layer ridge will
extend from the western atlantic across the florida peninsula into
the gulf of mexico through the period. A light westerly steering
flow with pwats remaining near 2 inches over NE fl SE ga will result
in scattered to numerous showers and thunderstorms each afternoon
and evening. Seabreeze fronts will merge over the interior with
storms producing locally heavy rainfall. Hot and humid conditions
will result in capes reaching 2000-3000 j kg each afternoon
according to GFS model soundings. Isolated strong storms will
produce strong gusty winds and frequent lightning strikes.

Temperatures and pops will be at or above normal.

Aviation Parting showers to the east near sgj early this morning
with low stratus and shallow ground fog potential at all sites
inland, especially where heavy rainfall occurred yesterday. Included
tempo ifr due to low stratus at vqq and gnv. Breezy onshore flow
will develop with gusts near 20 kts closer to the coast today with
waves of showers moving inland. Indicated vcsh at all terminals less
ssi where drier air will limit convection. Only indicated vcts at
gnv for now this afternoon.

Marine A front will meander across central florida today as
high pressure builds offshore of the mid-atlantic region with
breezy onshore flow today. The front will lift northward Thursday
as the high builds farther offshore of the atlantic coast with
winds veering to the ese. The high will will build east of the
florida peninsula the weekend as a front approaches from the
northwest with winds shifting ssw. Headlines are not expected with
combined seas generally 4 ft or less.

Rip currents: moderate risk of rip currents today due to elevated
onshore flow. Moderate risk advertised for SE ga coast Thu with
low risk for NE florida coast thu.

Hydrology Several area rivers are within action stage including
the south fork of black creek near penny farms. This site is
expected to crest within action stage (below flood stage) by early
afternoon today, pending no additional rainfall.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
